Used as a key intermediate in the synthesis of liquid crystalline materials and organic semiconductors. Its aldehyde functional groups allow for further chemical modifications, such as condensation reactions to form Schiff bases or extension into conjugated systems. The long dodecyloxy chains enhance solubility in organic solvents and promote self-assembly into ordered mesophases, making it suitable for applications in organic electronics, including organic field-effect transistors (OFETs) and photovoltaic devices. It is also employed in the development of stimuli-responsive materials and supramolecular architectures due to its rigid terphenyl core and tunable side chains.
